Patients suffering from manganism present a complex interplay between neurological and toxicological specialties. A less than normal level of manganese in men prompts situations of rashes, redness in skin, along with loss of pigments in hair and reduced serum cholesterol quantities. Manganese (Mn)-induced Parkinsonism has been well documented; however, little attention has been devoted to Mn-induced cardiovascular dysfunction. Early warning signs for welding fumes and manganese poisoning can include any or all of the following; muscle cramps, lethargy, insomnia, loss of equilibrium, weakness, In the first stage, patients are exhausted, apathetic, and weak, and may get, In sharp contrast to Parkinsonian patients, the present subjects have not shown, The patient had palpitations, hand tremor, lower limb myalgia, hypermyotonia, and a distinct. Apart from nervous system toxicity, the lungs, the heart, the liver and the reproductive system are also described as potential sites where harmful effects of manganese might be seen [3]. Bradykinesia, gait disturbances, rigidity and other extrapyramidal signs constitute the clinical presentation of most patients. The Canadian journal of neurological sciences. [4], The most often documented etiologies for the development of manganism include chronic total parenteral nutrition (TPN) use in critically ill patients, consumption of contaminated well-water, and exposure through work in welding, smelting, and mining. 2008 Jul; Zhang LL,Lu L,Pan YJ,Ding CG,Xu DY,Huang CF,Pan XF,Zheng W, Baseline blood levels of manganese, lead, cadmium, copper, and zinc in residents of Beijing suburb. Lancet (London, England). Early warning signs for welding fumes and manganese poisoning can include any or all of the following; muscle cramps, lethargy, insomnia, loss of equilibrium, weakness, headaches, and memory loss. A manganese level of 20 to 40 ppm (mg kg – ) in plant tissue is sufficient for most plants. Abstract. Symptoms of Manganese Toxicity. Supplementary to clinical criteria and laboratory studies, magnetic resonance imaging (MRI) of the endocranium shows a specific pattern of bilateral and symmetric hyperintensity of the globus pallidus at T1-weighted studies [7], implying that this procedure is a vital constituent of manganese poisoning workup [6]. Early neurological dysfunction was also a hallmark in these patients, characteristic of the basal ganglia/nigrostriatal system involvement. 2005 May; Moos T,Morgan EH, Transferrin and transferrin receptor function in brain barrier systems. [15] Knowledge of acceptable levels can assist patients in guiding the treatment of their home sources.

Environmental health perspectives. 2012 Feb 7; Koh J,Ito H, Differential diagnosis of Parkinson's disease and other neurodegenerative disorders. Neurology. [56][57] Once inside the CNS, Mn is circulated complexed with citrate and transported across membranes by the citrate transporter. The symptoms of manganese toxicity generally appear slowly over a period of months to years. Cordova FM,Aguiar AS Jr,Peres TV,Lopes MW,Gonçalves FM,Pedro DZ,Lopes SC,Pilati C,Prediger RD,Farina M,Erikson KM,Aschner M,Leal RB, Manganese-exposed developing rats display motor deficits and striatal oxidative stress that are reversed by Trolox. PloS one. Bodily efflux via biliary and pancreatic elimination may be dysfunctional depending on comorbid disease states or dietary variation.

[medical-dictionary.thefreedictionary.com], Besides an immune-mediated etiology, it is also believed to occur in gold, mercury, or manganese poisoning. Another street drug sometimes contaminated with manganese is the so-called "Bazooka", prepared by free-base methods from cocaine using manganese carbonate. Features of the language dysfunction variants include difficulties with daily life due to speech deficits, aphasia, speech apraxia, and other speech and comprehension impairments. Headaches. The toxic effects of manganese in dogs [5] and humans [6] tend to involve the heart, liver, and nervous system, but some endocrine effects can occur. 2006 Jun; Asanuma M,Miyazaki I,Ogawa N, Neuroprotective effects of nonsteroidal anti-inflammatory drugs on neurodegenerative diseases. In individuals with hepatic dysfunction, patients are at higher risk of Mn toxic accumulation in the bloodstream. Manganism was first described in the 19th and 20th centuries in several studies of miners by Couper and Rodier, respectively. Ingested Mn from plant sources is normally filtered through the liver, and the excess is removed to avoid toxicity. extract attenuates manganese-induced oxidative stress in rat primary astrocyte cultures. Manganese cytotoxicity is derived from the triggering of apoptosis in cells accumulating toxic doses of Mn. Journal of inherited metabolic disease. [114], Other neurodegenerative disorders, including Huntington disease, repeated and chronic head trauma, several infections such as syphilis, HIV, progressive multifocal leukoencephalopathy, structural brain disorders such as intraparenchymal masses or hydrocephalus, and metabolic disorders such as Wilson disease, hypoparathyroidism, chronic hepatic failure, and hemochromatosis. Neurotoxicology. Magnesium Deficiency & Toxicity Symptoms Magnesium is a major mineral needed by your body for a number of processes. [14] Current US guidelines suggest a measured Mn level in drinking water of fewer than 400 micrograms of Mn per liter. Given that Mn is primarily removed via biliary mechanisms, urinary levels are significantly low at baseline and do not reliably correlate with serum toxic levels. Analysis of their cohort yielded no improved steadiness of the hands and no improvement in reaction time. In the setting of the above risk factors and exposure history, identification of the characteristic symptomatology should raise the alarm for Mn. Toxicology letters. Journal of biomedical science. In rat studies, Mn blood levels reached a steady-state concentration in approximately one month, while CNS levels continued to rise to about two months.[65]. [83], In the context of recent or on-going exposure, MRI has also proven to be clinically useful alongside novel bone scanning. Chronic manganese intoxication has an insidious and progressive course and usually starts with complaints of headache, fatigue, sleep disturbances, irritability and emotional instability. bone growth, protection from free radicals, protein metabolism, etc.) Levin J,Kurz A,Arzberger T,Giese A,Höglinger GU, The Differential Diagnosis and Treatment of Atypical Parkinsonism.

Wennberg et al. Once the call has been placed, request to discuss your patient's case with the on-call Toxicologist for optimal treatment guidance. DMT-1 proteins are represented highly within the basal ganglia, which contributes to the substantially elevated levels of Mn in conditions of excess. [67] Other symptoms reported in a case study from Beijing included memory impairment and insomnia. [99][100][101][102], Newer therapies being investigated include the use of taurine and Rasagiline. 7. 1977 Mar 25; Filipov NM,Dodd CA, Role of glial cells in manganese neurotoxicity. The most accessible form of treatment for manganism is the removal of the patient from the source exposure, whether the source is occupational, environmental, or iatrogenic. Overall, the prognosis is more related to morbidity than mortality and is overall favorable once removed from the exposure setting. The progression of manganism includes: Behavioral Changes - Symptoms include fatigue. Early psychiatric symptoms followed by neurologic deterioration similar to that of Parkinson disease are the hallmark of toxicity. Symptoms on older leaves begin with the appearance of small,irregularly shaped patches of pale tissue in interveinalzones. 2009 Nov; Lee JW,Lee CK,Moon CS,Choi IJ,Lee KJ,Yi SM,Jang BK,Yoon BJ,Kim DS,Peak D,Sul D,Oh E,Im H,Kang HS,Kim J,Lee JT,Kim K,Park KL,Ahn R,Park SH,Kim SC,Park CH,Lee JH, Korea National Survey for Environmental Pollutants in the Human Body 2008: heavy metals in the blood or urine of the Korean population. Environmental health : a global access science source. [41] Mn also induces the production of reactive oxygen species within mitochondria, resulting in an increase in apoptotic protein expression and an increase in intracellular antioxidant proteins to attenuate the cascade.[42][43]. In addition to occupational exposure, many studies have confirmed that industrial emissions that contain manganese contaminate air, soil, plants and even water sources, which predisposes a number of individuals to manganese toxicity through inhalation or ingestion, particularly those living in close proximity to these industries [1] [4] [6]. Manganese poisoning is primarily seen in the occupational setting, as numerous industries use manganese ore for the production of batteries, ceramics, steel, etc. A detailed patient history and a full biochemical workup are necessary to make the diagnosis. [25][44][45][46][47] Despite Parkinson disease being a disease of primarily dopaminergic dysfunction, these main mechanisms of disease are not identical in manganism. [69] Animal studies have shown that overexposure to Mn causes hemodynamic changes, including hypotension and bradycardia, concomitant with a prolonged PR and QRS interval. This compound allows the phasing out of leaded gasoline, but concomitantly puts individuals at risk for manganism in the settings of chronic and excessive exposures.[20]. O’Neal SL, Zheng W. Manganese Toxicity Upon Overexposure: a Decade in Review. In women, a manganese deficiency displays prominent mood swings like in the case of cyclothymia, besides complications of premenstrual syndrome. 2014 Aug 17; Jankovic J, Searching for a relationship between manganese and welding and Parkinson's disease. So, the correct answer is … Early symptomatology of manganism involves changes in the patient's psychiatric and emotional state. Providing Manganese during TPN helps prevent development of deficiency symptoms such as nausea and vomiting, weight loss, dermatitis and changes in growth and color of hair. [3] These adverse effects are secondary to its deposition in specific components of the basal ganglia and alteration of dopaminergic neuronal enzyme activity. 2017 Jun; O'Neal SL,Zheng W, Manganese Toxicity Upon Overexposure: a Decade in Review. Taurine use decreases the toxic effects of Mn in vitro, mostly through the preservation of mitochondrial functionality in CNS tissues. Neil et al. 2007 Jan; Robison G,Zakharova T,Fu S,Jiang W,Fulper R,Barrea R,Marcus MA,Zheng W,Pushkar Y, X-ray fluorescence imaging: a new tool for studying manganese neurotoxicity. Manganese (Mn) toxicity in plants is often not a clearly identifiable disorder. Mn, as described previously, preferentially accumulates within basal ganglia structures. Specific deficits that remained included poor performance on simple and alternating movements, drawing ability, and diminished hand stability. 2013 May; Aschner M,Gannon M, Manganese (Mn) transport across the rat blood-brain barrier: saturable and transferrin-dependent transport mechanisms. Journal of neurology. [15][16], Infants who are breastfed obtain their necessary nutritional requirements of Mn without risk for toxicity. The patient may experience personality changes concomitant with periods of rapid emotional fluctuations, which need to be qualitatively differentiated from the patient's baseline. [69] Severe symptoms include the "cock-walk" described in the earliest Mn studies, which is characterized by patients walking on their toes with a forward tilt as they move. [30] This ability of oxidized Mn to be carried via transferrin is one of the means that Fe deficiency contributes to manganism, given that transferrin levels are increased in the setting of iron deficiency. Features of this syndrome include vertical supranuclear palsy and parkinsonian symptoms. Early cognitive deficits include short term memory difficulties, multi-tasking deficits, and visuospatial deficiencies. A child on long-term total parenteral nutrition (TPN) lacking manganese developed bone demineralization and impaired growth that were corrected by man… [16] Bradyskinesia Olanowet al. Investigative radiology. The gliosis is associated with an increased number of astrocytes showing an enlarged and irregular nucleus. [21], Bone is a natural Mn sink, thus making it an ideal organ to study the effects of exposure to the natural metal. In another follow-up study by Roels et al., workers from a battery manufacturing plant were followed for eight years after cessation of Mn exposure. In the setting of excessive exposure, however, toxic effects are exerted in the body. In humans, manganese toxicity represents a serious health hazard, resulting in severe pathologies of the central nervous system. Manganese toxicity mainly affects the central nervous system and can cause tremors, muscle spasms, tinnitus, hearing loss, and the feeling of being unsteady on one’s feet [ 1, 2 ]. [71][72], Focusing on the patient's social history can confirm the diagnosis in patients suspected of having manganism. This syndrome can easily be mistaken for manganism in its early stages if behavioral symptoms predominate, given manganism’s early neuropsychiatric manifestations. [81] More recent research suggests a reasonable correlation between Mn exposure and hair and nails Mn levels while supplementing the notion that salival levels do not correlate well with exposures. On microscopic examination gliosis can be noticed both in GP and, even if in a less degree, in SNr. Variables measured included hand steadiness and reaction time. Manganese toxicity is unique neurotoxicity that progresses from early psychiatric abnormalities to symptoms reminiscent of Parkinson disease, such as postural deficiencies, bradykinesia, shuffling gait, mask-like facies, micrographia, and speech difficulties. [70] Other severe symptoms are worsening tremor and dystonic movements of extremities. Frequency of symptoms associated with manganese toxicity. The high concentrations in the liver and pancreas are likely related to their roles in excretion. 2009 Feb; Grashow R,Zhang J,Fang SC,Weisskopf MG,Christiani DC,Cavallari JM, Toenail metal concentration as a biomarker of occupational welding fume exposure. As the diseases progress to the late stage, the patient shows symptoms similar to Parkinson’s disease (PD), which include problems with gait and balance, rigidity, tremors, slowed speech, weakness, and monotone. Neurotoxicology. in 2005 showed that individuals who were exposed that were at least greater than or equal to 45 years old had persistent cognitive deficits after cessation of toxic exposure to Mn.[119][120]. 2000;21(5):769-775.
